Finds or adds anFMassReplicationEntityInfoto the EntityInfoMap for an Entity with NetWorkID. This will update the ReplicationID if an older one is found but it does not change theFMassReplicationEntityInfo::Entitymember. Returns whether we added an entry in EntityInfoMap, or if the found item has an older or newer ReplicationID than that that is passed in. We shouldn't actually get an equal ReplicationID, but in this case we'll treat the existing EntityInfoMap entry as newer.SetEntity()must be called soon after this if the entity handle is !IsSet()
